The microbial genomics of glacier-fed streams: adaptations to an extreme ecosystem

Glacier-fed streams are the cold, ultra-oligotrophic, and unstable streams that are fed by glacial meltwater. Despite these extreme conditions, they harbour a diverse and abundant microbial diversity that develops into biofilms, covering the boulders and s ...

Identifying and Characterizing Trans Women in the Swiss HIV Cohort Study as an Epidemiologically Distinct Risk Group

Jacques Fellay

Background As trans women are disproportionately affected by the HIV epidemic, and are still understudied, we aimed to identify and characterize the trans women in the Swiss HIV Cohort Study (SHCS). Methods A combination of criteria from pre-existing cohor ...

Microdiversity characterizes prevalent phylogenetic clades in the glacier-fed stream microbiome

Tom Ian Battin, Hannes Markus Peter, Tyler Joe Kohler, Susheel Bhanu Busi, Stylianos Fodelianakis, Massimo Bourquin, Jade Brandani, Paraskevi Pramateftaki, Matteo Tolosano, Vincent Henri De Staercke, Michail Styllas

Glacier-fed streams (GFSs) are extreme and rapidly vanishing ecosystems, and yet they harbor diverse microbial communities. Although our understanding of the GFS microbiome has recently increased, we do not know which microbial clades are ecologically succ ...

Hand pose selection in a bimanual fine-manipulation task

Aude Billard, Kunpeng Yao

Many daily tasks involve the collaboration of both hands. Humans dexterously adjust hand poses and modulate the forces exerted by fingers in response to task demands. Hand pose selection has been intensively studied in unimanual tasks, but little work has ...

The foreign oligochaete species Quistadrilus multisetosus (Smith, 1900) in Lake Geneva: morphological and molecular characterization and environmental influences on its distribution

Benoît Jean Dominique Ferrari, Régis Lionel Vivien

The presence of the oligochaete species Quistadrilus multisetosus (Smith, 1900) originating from North America has been mentioned for several decades in Europe, the Middle East and Russia. Its distribution and abundance in Europe is still unknown but it ca ...

From the product to the process: Fine-scale skeletal structures of scleractinian corals and their relevance to biomineralization models, geochemical sampling strategies, and phylogenetic reconstructions

Anders Meibom, Jaroslaw Hubert Stolarski

Interpretation of biomineralization processes based solely on the end product - the skeleton - may seem abreakneck task. This is because the biologically controlled mineralization involves cascades of intermediatephases and the activity of a myriad of orga ...

Delta-Notch signalling in segmentation

Andrew Charles Oates

Modular body organization is found widely across multicellular organisms, and some of them form repetitive modular structures via the process of segmentation. It's vastly interesting to understand how these regularly repeated structures are robustly genera ...

Genetic diversity of two Daphnia-infecting microsporidian parasites, based on sequence variation in the internal transcribed spacer region

Stefan Jean Laurent

Background: Microsporidia are spore-forming obligate intracellular parasites that include both emerging pathogens and economically important disease agents. However, little is known about the genetic diversity of microsporidia. Here, we investigated patter ...

Divergent PCB organohalide-respiring consortia enriched from the efflux channel of a former Delor manufacturer in Eastern Europe

Christof Holliger, Luiz Felippe De Alencastro, Pierre Rossi, Martina Praveckova

Polychlorinated biphenyl (PCB) organohalide-respiring communities from the efflux channel of a former Delor manufacturer in Eastern Slovakia were assessed using metagenomic, statistical and cultivation-adapted approaches. Multivariate analysis of environme ...

Inferring the Evolutionary History of Primate microRNA Binding Sites: Overcoming Motif Counting Biases

Jeffrey David Jensen

The first microRNAs (miRNAs) were identified as essential, conserved regulators of gene expression, targeting the same genes across nearly all bilaterians. However, there are also prominent examples of conserved miRNAs whose functions appear to have shifte ...

Study of cell differentiation by phylogenetic analysis using histone modification data

Bernard Moret, Philipp Bucher, Yu Lin, Nishanth Ulhas Nair

Background: In cell differentiation, a cell of a less specialized type becomes one of a more specialized type, even though all cells have the same genome. Transcription factors and epigenetic marks like histone modifications can play a significant role in ...

Mycobacterium leprae genomes from a British medieval leprosy hospital: towards understanding an ancient epidemic

Stewart Cole, Pushpendra Singh

Background: Leprosy has afflicted humankind throughout history leaving evidence in both early texts and the archaeological record. In Britain, leprosy was widespread throughout the Middle Ages until its gradual and unexplained decline between the 14th and ...

Superinfection with drug-resistant HIV is rare and does not contribute substantially to therapy failure in a large European cohort

Istvan Bartha

Background: Superinfection with drug resistant HIV strains could potentially contribute to compromised therapy in patients initially infected with drug-sensitive virus and receiving antiretroviral therapy. To investigate the importance of this potential ro ...

TIBA: a tool for phylogeny inference from rearrangement data with bootstrap analysis

Bernard Moret, Yu Lin, Vaibhav Rajan

TIBA is a tool to reconstruct phylogenetic trees from rearrangement data that consist of ordered lists of synteny blocks (or genes), where each synteny block is shared with all of its homologues in the input genomes. The evolution of these synteny blocks, ...
